A combined ventilation mast suitable for an ammonia fuel powered ship is composed of a main ventilation mast and two sets of auxiliary ventilation masts, the two sets of auxiliary ventilation masts are the first auxiliary ventilation mast set and the second auxiliary ventilation mast set respectively, the first auxiliary ventilation mast set is composed of a plurality of first auxiliary ventilation masts, and the second auxiliary ventilation mast set is composed of a plurality of second auxiliary ventilation masts. The first auxiliary ventilation mast group is composed of a plurality of first auxiliary ventilation masts, the second auxiliary ventilation mast group is composed of a plurality of second auxiliary ventilation masts, the number of the first auxiliary ventilation masts is the same as that of the second auxiliary ventilation masts, the first auxiliary ventilation masts and the second auxiliary ventilation masts are alternately arranged in the circumferential direction of the main ventilation mast, the heights of the first auxiliary ventilation masts are sequentially reduced, and the heights of the second auxiliary ventilation masts are sequentially reduced. And in the first auxiliary ventilation mast group, the first auxiliary ventilation mast with the lowest height is higher than the second auxiliary ventilation mast with the highest height in the second auxiliary ventilation mast group. The staggered lowering mode helps all the auxiliary air outlets to be staggered to the maximum degree in height and angle, so that secondary diffusion of toxic areas caused by pressure difference among all the ventilation pipelines when ammonia gas leaks is avoided.
一种适用于氨燃料动力船的组合式透气桅,组合式透气桅由一个主透气桅和两组副透气桅组成,两组副透气桅分别是第一副透气桅组和第二副透气桅组,第一副透气桅组由多个第一副透气桅组成,第二副透气桅组由多个第二副透气桅组成,第一副透气桅的数量和第二副透气桅的数量相同,多个第一副透气桅和多个第二副透气桅交替设置在主透气桅的周向,多个第一副透气桅的高度依次降低,多个第二副透气桅的高度依次降低,第一副透气桅组中,高度最低的第一副透气桅,高于,第二副透气桅组中,高度最高的第二副透气桅。这种交错降低的方式帮助各个副出风口在高度和角度上得以最大程度的错落开来,以避免氨气泄漏时各个通风管道之间由于压差导致的毒区二次扩散。
